CBN Introduces Stress Tests and Capital Buffers Post-Recapitalisation to Bolster Bank Risk Management

Following the successful conclusion of the banking sector recapitalisation exercise, the Central Bank of Nigeria (CBN) is shifting its focus to the next stage of regulatory oversight. It plans to introduce a more robust risk management framework, which will be centred on stress testing and stricter capital regulations.

The apex bank announced that this new approach is designed to build upon the achievements of the recapitalisation programme and ensure that banks can withstand potential shocks, whether they stem from macroeconomic shifts or industry-specific challenges.

Dr. Olubukola Akinwunmi, the Director of Banking Sector Supervision at the CBN, revealed in a recent interview with ARISE NEWS Channel that the bank has bolstered its risk-based capital adequacy framework. This involves requiring deposit money banks to perform regular stress tests under various defined conditions and to maintain sufficient capital reserves to cover potential losses.

Akinwunmi elaborated on the measures, stating, "To safeguard these gains, the CBN has strengthened its risk-based capital adequacy framework, requiring banks to conduct regular stress testing across defined scenarios and maintain appropriate capital buffers."

He further added, "Key regulatory measures, including prudential guidelines and the supervisory framework, are subject to periodic review to support ongoing strengthening of governance, risk management, and sector resilience."

Regarding the timing of capital adequacy, Akinwunmi commented, "We don’t have to wait for another 20 years or 30 years before we ensure that our banks are adequately capitalised."

He explained the stress testing process: "Now, the stress testing framework requires that banks create scenarios that could happen where there is a deterioration in their loan books. So, if there is any shock, domestic or external, that affects the economic agents that they are lending to households, consumers, businesses and it happens to impact their ability to repay, that means the bank may be exposed to taking some losses."

"What the risk-based capital requirement, founded upon the stress testing framework, says is that, on an ongoing basis, banks will assess their exposure to risk based on a gradual deterioration of their loan book," he continued.

"And that gradual deterioration of the loan book is a scenario-based deterioration to determine the gap that may be there for banks to proactively respond by raising additional capital, or perhaps proper planning of their loan books to ensure that the capital they have is properly managed to meet the demands of their risk exposure."

"The essence of the stress testing framework, and the intent is to ensure that banks proactively manage the capital required, their capital adequacy, and meet it when necessary, raise adequate fresh capital that is required to maintain capital adequacy," Akinwunmi concluded.

Industry analysts have responded positively to the central bank's initiative, interpreting it as a shift from merely raising capital to focusing on its preservation and effective utilisation. They believe the regulators aim to prevent a recurrence of past issues involving asset quality decline and inadequate risk controls.
